Containing Toluene

ScienceHideout - 24-9-2011 at 15:53

Last time I arranged my chems, I (appropriately) put my toluene in my flammables cabinet instead of on the shelf where it was previously. When I opened the cabinet yesterday to get some alcohol, I was overwhelmed by the smell of toluene. I decided to enclose the can (1L) in a ziplock bag and put it back. However, I still notice the smell in my chem cabinet.

Any tips on containing and controlling toluene and its gases?

I have had 1 liter of toluene in a metal bottle with a HDPE screw cap in my cupboard for about a year and have never noticed any leakage. Either your container is not suitable for the solvent, or you spilled some down the side or something and it evaporated in your cabinet. Put it in a properly sealed container and vent the cabinet of the lingering fumes.

My toluene was purchased in a metal can with a metal top. It has only been used a couple of times, and I haven't used it for a couple weeks. I got rid of the fumes- but they always come back. The can is very tightly capped...

Check for leaks or holes in the can. Put some Teflon thread tape on the male cap piece. Then wash the can with a damp soapy rag.

It doesn't appear to be leaking... I will try the PTFE...

PTFE, always. It's the number one choice for just about anything.
